What are the tests done by Cardiologists in Sydney?

Cardiologists in Sydney are medical practitioners who specialize in studying and treating heart conditions. This article will explore what a cardiologist does and the various types of cardiology treatments they can perform. If you may require treatment from a cardiologist, contact us today for more information on how we can help you.

Cardiac Catheterization (Heart Cath)

Cardiac catheterization is a test to look at the heart. It involves inserting a thin tube called a catheter into your blood vessels and moving it through your bloodstream until it reaches your heart. The procedure can be used to diagnose or treat many different heart problems, such as:

  • heart specialist Sydney

Heart rhythm problems – for example, irregular heartbeats (arrhythmias) or slow heart rate (bradycardia)
  • Blood clotting – for example, deep vein thrombosis (DVT) and pulmonary embolism (PE)
  • Blood vessel damage – for example, coronary artery disease and peripheral artery disease

Coronary Angiography by heart specialist Sydney

Coronary angiography is the most accurate test for diagnosing coronary artery disease. It allows the heart specialist Sydney to evaluate blood flow through the arteries that supply oxygen-rich blood to your heart muscle and determine if there are any blockages in these vessels that could lead to a heart attack or stroke.

Benefits of coronary angiography

A coronary angiogram is an essential tool in diagnosing coronary artery disease (CAD), which can cause chest pain and result in death if not treated on time. A coronary angiogram will give you an idea of whether you have CAD. If so, it also helps determine how severe your condition is and what treatment options may be available for treating it. Risks or side effects associated with coronary angiography procedure include infection at the wound site; bleeding at the wound site; allergic reaction during sedation; irregular heartbeat after catheterization; excessive bleeding after catheterization due to clotting disorders or anticoagulant therapy (blood thinners); temporary loss of consciousness while under sedation; kidney damage resulting from contrast dye used during procedures; allergic reaction due to trace metals contained within dyes used during operations.

Coronary artery bypass surgery (CABG)

Coronary artery bypass surgery (CABG) is a surgical procedure to treat coronary heart disease. In this type of surgery, the surgeon bypasses (or takes around) narrowed or blocked blood vessels of the heart with new blood vessels called grafts. The goal of CABG is to improve blood flow so that your heart can work more effectively. Cardiologists in Sydney recommend CABG for patients who have:

  • One or more blocked or partially blocked arteries that need to be opened up because they’re causing chest pain or shortness of breath.
  • Two or more blocked arteries are causing symptoms, and it’s impossible for doctors to clear one blockage without opening up another one first (this is common if you’ve had a previous heart attack).

Electrophysiology Study (EP Study)

An EP study is used to diagnose and treat heart rhythm problems. It’s done under sedation in a unique laboratory called an electrophysiology laboratory (EP lab). The doctor inserts a catheter into your groin and threads it up through the veins of your leg to the heart. Your doctor will use this device to shock your heart back into a normal rhythm if abnormal rhythms are found during testing. This procedure is called ablation, which means destroying or removing tissue that causes abnormal rhythms to prevent them from returning later. The EP study also determines why your heart beats too fast or has abnormal rhythms. You may have the test if: -You have symptoms of a heart rhythm problem, such as palpitations or fainting spells -You’ve had an abnormal EKG finding that suggests electrical issues in your heart.

Holter monitor test Sydney or Ambulatory Blood Pressure Monitor

Holter monitor test Sydney involves a portable device used to measure the electrical activity of your heart. A doctor may use this device to check for irregular heart rhythms, or it can be used to monitor someone who has already been diagnosed with arrhythmia. The ambulatory blood pressure monitor (ABPM) measures your blood pressure throughout the day and night. It’s usually worn on your upper arm, like a regular cuff-based home blood pressure monitor. The ABPM allows doctors to see how high your systolic and diastolic pressures are at different times of the day, which is essential for diagnosing hypertension and other conditions that increase the risk of heart disease or stroke.

Nuclear Scans, cardiac and bone scans

Nuclear scans are a way of detecting diseases in the heart and bones. Nuclear scans help diagnose coronary artery disease, heart muscle, and bone diseases. They can also be used to assess the heart’s function (ejection fraction) and to determine if there is an obstruction in one or more coronary arteries. Nuclear scans are usually done on a small amount of blood injected into a vein. The blood circulates throughout the body and is absorbed by bone or heart tissue in proportion to their needs. The amount of radioisotope present in each organ or tissue can be measured with a scanner.

Pacemaker Implantation or Defibrillator Implantation

Pacemaker implantation is a surgical procedure to treat abnormal heart rhythms, including bradycardia (abnormally slow heartbeat) and atrial fibrillation. Pacemaker implantation is usually performed under general anaesthetic, and the pacemaker is implanted in the chest, near the heart.

Percutaneous Coronary Intervention (PCI) / Angioplasty / Stenting

  • Percutaneous Coronary Intervention or Angioplasty: A procedure that uses a small catheter to open up blocked arteries and improve blood flow to the heart muscle.
  • Coronary Artery Bypass Graft (CABG): The insertion of a vein or artery from another part of the body into your heart’s coronary arteries to bypass blockages, which improves your ability to exercise and reduces angina.
  • Percutaneous Coronary Intervention (PCI), also known as angioplasty: Is a minimally invasive procedure used to treat narrowed coronary arteries without surgery.
